Fix audio sample rate forced to 48 kHz for non-Opus codecs

2026-06-21T07:43:31Z

GetProgressiveAudioFullCommandLine applied the libopus-only sample rate quantization to every codec except Opus, inverting the intended guard. A requested rate such as 44100 Hz was therefore snapped to 48000 Hz for AAC/MP3/FLAC, while Opus (which actually requires the quantization) was skipped entirely. Apply the quantization only when the output codec is Opus, and pass the requested sample rate through unchanged for all other codecs. Fixes #17026 Co-Authored-By: Claude Opus 4.8

Normalize VobSub .sub to .idx for embedding, add EncodingHelper tests

2026-05-19T11:03:07Z

Move the .sub to .idx path normalization outside the burn-in check so it applies to subtitle embedding as well. ffmpeg requires the .idx file to read VobSub subtitles. Add unit tests for GetMapArgs and GetInputArgument covering internal subs, external SRT, multi-file SRT, multi-stream MKS containers, and VobSub .sub/.idx path normalization.

Fix external subtitle stream mapping for multi-stream containers

2026-05-19T11:03:07Z

Compute the in-file stream index for external subtitles instead of hardcoding -map 1:0. For single-stream files (SRT/ASS/VTT) the index is always 0, preserving existing behavior. For multi-stream containers like MKS, the correct track is selected by counting sibling streams that share the same Path. Add unit tests for GetMapArgs covering internal subs, external SRT, multiple external files, and multi-stream MKS containers.
